Abstract

In various embodiments, the invention involves methods and systems suitable for roadway monitoring, mapping, and maintenance. The probability of a road distress is calculated by combining various sources of data, and automatic alerts are generated to request mobilization of a road repair resource. Various methods are included to increase the accuracy of the probability calculations.

First claim

What is claimed is:

1. A method for determining the location of a road distress, comprising:
measuring, by a mobile sensor, a distress data for a road section, wherein the distress data comprises a distress time component and a distress action component;
identifying a relevant traffic data for the road section, the relevant traffic data comprising a traffic time component that corresponds to the distress time component;
calculating a probability of a road distress on the road section based on the distress data and relevant traffic data; and
responsive to the calculated probability exceeding a predetermined threshold probability, generating an alert identifying the road section;

wherein:
the road distress comprises at least one of a hole, a swell, a rock, and debris;
the distress data pertains to a first lane in the road section, and the traffic data pertains to a second lane in the road section, the first lane being adjacent to the second lane;
the distress data comprises a rapid deviation in an x-y plane followed by a rapid return to an initial trajectory for a vehicle in the first lane; and
the traffic data comprises a lack of any vehicles in the second lane at the traffic time component that corresponds to the distress time component.

2. The method of claim 1 , wherein the mobile sensor is integral with a vehicle, or wherein the mobile sensor is integral with a mobile device, the mobile device disposed in the vehicle.

3. The method of claim 1 , further comprising communicating the distress data to a remote server, via a network, and further comprising communicating the alert via a network.

4. The method of claim 1 , wherein the relevant traffic data is identified from a plurality of traffic data for the road section, wherein the plurality of traffic data is indexed by a traffic time component.

5. The method of claim 1 , wherein the relevant traffic data is identified from a plurality of traffic data for the road section, wherein the plurality of traffic data is indexed by a traffic time component, and wherein the method further comprises receiving, by the remote server via a network, the plurality of traffic data.

6. The method of claim 1 , wherein the distress data further comprises a distress lane indicator and a distress direction component, and wherein the traffic data further comprises a traffic lane indicator and a traffic direction component.

7. The method of claim 1 , wherein the probability is determined by a remote server, and wherein the remote server receives a plurality of distress data from the mobile sensor, and wherein the method further comprises identifying a relevant distress action in the distress data.

8. The method of claim 1 , wherein the mobile sensor is integral with a vehicle, or wherein the mobile sensor is integral with a mobile device, the mobile device disposed in the vehicle, and wherein the relevant traffic data is identified from a plurality of traffic data for the road section, wherein the plurality of traffic data is indexed by a traffic time component.

9. The method of claim 1 , wherein the alert is configured to initiate a road distress avoidance measure in a vehicle.

10. The method of claim 1 , wherein the alert is a machine-readable instruction configured to initiate a road distress avoidance measure in a vehicle when the vehicle enters the identified road section, and wherein the method further comprises adding the alert to a database of alerts.

11. A computer system for determining the location of a road distress, comprising:
a processor;
a memory coupled to the processor, the memory configured to store program instructions executable by the processor to cause the computer system to:
receive, from a mobile sensor, a distress data for a road section, wherein the distress data comprises a distress time component and a distress action component;
identify a relevant traffic data for the road section, the relevant traffic data comprising a traffic time component that corresponds to the distress time component;
calculate a probability of a road distress on the road section based on the distress data and relevant traffic data; and
responsive to the calculated probability exceeding a predetermined threshold probability, generate an alert identifying the road section;

wherein:
the road distress comprises at least one of a hole, a swell, a rock, and debris;
the distress data pertains to a first lane in the road section, and the traffic data pertains to a second lane in the road section, the first lane being adjacent to the second lane;
the distress data comprises a rapid deviation in an x-y plane followed by a rapid return to an initial trajectory for a vehicle in the first lane; and
the traffic data comprises a lack of any vehicles in the second lane at the traffic time component that corresponds to the distress time component.

12. The computer system of claim 11 , wherein the relevant traffic data is identified from a plurality of traffic data for the road section, wherein the plurality of traffic data is indexed by a traffic time component.

13. The computer system of claim 11 , wherein the mobile sensor is integral with a vehicle, or wherein the mobile sensor is integral with a mobile device, the mobile device disposed in the vehicle.

14. The computer system of claim 11 , wherein the mobile sensor is integral with a vehicle, or wherein the mobile sensor is integral with a mobile device, the mobile device disposed in the vehicle, and wherein the relevant traffic data is identified from a plurality of traffic data for the road section, wherein the plurality of traffic data is indexed by a traffic time component.

15. The computer system of claim 11 , wherein the alert is configured to initiate a road distress avoidance measure in a vehicle.

16. The computer system of claim 11 , wherein the alert is a machine-readable instruction configured to initiate a road distress avoidance measure in a vehicle when the vehicle enters the identified road section, and wherein the method further comprises adding the alert to a database of alerts.

17. A method for managing road repair resources, the method comprising:
calculating a probability of a road distress in a road section by combining sensor data from a mobile sensor with relevant traffic data; and
automatically alerting a road repair resource to request repair of the road section when the calculated probability of a road distress exceeds a predetermined threshold probability.

18. The method of claim 17 , wherein the sensor data pertains to a first lane in the road section, and wherein the traffic data pertains to a second lane in the road section, the first lane being adjacent to the second lane.

19. The method of claim 17 , wherein the distress data pertains to a first lane in the road section, and wherein the traffic data pertains to a second lane in the road section, the first lane being adjacent to the second lane, and wherein the relevant traffic data is identified from a plurality of traffic data for the road section, wherein the plurality of traffic data is indexed by a traffic time component.

20. The method of claim 17 , wherein the mobile sensor is integral with a vehicle, or wherein the mobile sensor is integral with a mobile device, the mobile device disposed in the vehicle, and wherein the relevant traffic data is identified from a plurality of traffic data for the road section, wherein the plurality of traffic data is indexed by a traffic time component.
